Shadow Lawn's historical significance stems from the architecture of its houses. The district features a number of dwellings with modest Tudor Revival detailing characteristic of historicist "cottage" bungalows built in the 1930s. The dominance of this architectural form is an important feature that distinguishes the district from nearby housing clusters, as no other area in the northern suburbs of Austin contains as high a concentration of Tudor Revival dwellings. Unlike the bungalows in the nearby Hyde Park Historic District, these houses utilized more expensive masonry veneer rather than cheaper wood siding.[3]
